Abstract: An offset outlet flush valve has a valve body, the valve body having an inlet comprising an inlet aperture, an overflow tube socket comprising an overflow tube aperture, and an outlet comprising an outlet aperture. The outlet aperture of the valve body, and the wall that defines it, intersects a portion of the inlet aperture and a portion of the overflow tube aperture and the walls that define them. In this way, a water flow continuum is created between the inlet aperture and the outlet aperture and between the overflow tube aperture and the outlet aperture. A number of alternative embodiments of an overflow tube socket and overflow tube are also provided depending upon OEM or after-market application of the offset outlet flush valve.

Abstract: An improved fill valve has a pivot valve body that is pivotally suspended immediately below a float housing and is movable between two positions. In a first position, the pivot valve body blocks the flow of water from the float housing. In a second position, the pivot body allows the flow of water from the float housing. The pivot valve body has two top compartments, each separated from the other by a wall. The first compartment retains an amount of water in it. The second compartment functions as a water flow restriction apparatus and includes an upwardly-extending member for sealing off a check valve that is disposed within the bottom of the float housing. The fill valve also includes structural elements that allow the water to trickle into the float housing at a very slow rate. The fill valve can be re-set for normal toilet tank operation.

Abstract: The present invention provides an improved top mounted toilet flush valve and a method for installing the flush valve that can be readily adapted to the tank profile of a wide variety of gravity operated flush toilets. More specifically, in accordance with the objectives of the present invention, there is provided a flush valve having an overflow tube that is adjustable in height and a method for adjusting the overflow tube.

Abstract: A toilet flapper valve has a rigid bulb insert and a surrounding flapper top, the latter being preferably made of an elastomeric material. The flapper valve of the present invention can be used as equipment in toilets of original manufacture and as replacement after-market devices.

Abstract: A top mounted flush valve is provided for installation in a blind drain hole in the bottom wall of a toilet tank of a conventional one-piece gravity operated toilet. The flush valve includes a generally cylindrical valve body sized for insertion through the drain hole from the upperside of the bottom wall of the tank. A seal member on an underside of the valve body provides a watertight seal between the valve body and an upperside of the bottom wall of the tank. A generally cylindrical drive collar is rotatable within a central aperture of the valve body. A generally cylindrical spring nut has a threaded portion engaged with a threaded portion of the drive collar so that the drive collar can be screwed to generate relative movement between the drive collar and the spring nut along a longitudinal axis substantially perpendicular to the bottom wall of the tank.
